Android的NDK：包括提升C ++库(Android NDK: Including boost

我试图用一个Boost库我的Android应用程序中，使用NDK。我已经发现一对夫妇的成功案例在这里和这里，但我不能说我的一样。我特别想使用的库在这个环节，以及升压线程库。在下面的代码，我只是想包括线程库，而不是数学库。我用来构建Boost库的过程是几乎相同的，因为我附第一个链接。

到目前为止，似乎我已经成功地构建了Boost库，但是当我运行ndk-build ，我得到以下错误：

Prebuilt       : libboost_thread.a <= <NDK>/sources/
cp: omitting directory `path/to/ndk/sources/boost'
make: *** [obj/local/armeabi/libboost_thread.a] Error 1

显然， cp: omitting directory...是不完全的错误。但我发现了比其他的唯一事情是下一行，这并不真正意味着什么。 Error 1

这是我的Android.mk文件：

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_STATIC_LIBRARIES := boost_thread
LOCAL_LDLIBS := lboost_system-gcc-md lboost_thread-gcc-md -lgnustl_static
LOCAL_LDLIBS += lboost_system-gcc-md lboost_thread-gcc-md \
         -L$(NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/libs/armeabi \
         -lgnustl_static  
LOCAL_SRC_FILES := #cpp_sources
LOCAL_MODULE := com_example_ndkFile_CppMethods
include $(BUILD_SHARED_LIBRARY)
$(call import-module,boost)

还有还有在Android.mk文件path/to/ndk/sources/boost/ ：

LOCAL_PATH:= $(call my-dir)  
include $(CLEAR_VARS)  
LOCAL_MODULE:= boost_thread
LOCAL_SRC_FILES:= android/lib/libboost_thread.a  
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)  
include $(PREBUILT_STATIC_LIBRARY)

而我卑微Application.mk文件：

APP_ABI := armeabi armeabi-v7a
APP_STL := gnustl_static
APP_CPPFLAGS = -fexceptions

我内置使用Boost库bjam 。所有的libboost_###.a文件是在sources/boost/android/lib文件夹中。

什么是我得到的错误？

Answer 1:

我内置使用Boost库升压换的Android 。然后，我在我的升压/包括/ lib目录中的Android makefile文件boost.mk

LOCAL_PATH := $(call my-dir)

# boost_date_time
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_date_time
LOCAL_SRC_FILES := libboost_date_time-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_filesystem
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_filesystem
LOCAL_SRC_FILES := libboost_filesystem-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_thread
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_thread
LOCAL_SRC_FILES := libboost_thread-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_system
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_system
LOCAL_SRC_FILES := libboost_system-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_program_options
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_program_options
LOCAL_SRC_FILES := libboost_program_options-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_chrono
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_chrono
LOCAL_SRC_FILES := libboost_chrono-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

我的模块在这里我使用一些Boost库的看起来是这样的

LOCAL_PATH := $(call my-dir)

# SignalServer, executable 
#
include $(CLEAR_VARS)
LOCAL_CFLAGS           := -DTIXML_USE_TICPP
#LOCAL_CFLAGS           += -DDEBUG
LOCAL_STATIC_LIBRARIES := boost_thread \
    boost_system \
    boost_filesystem \
    boost_program_options \
    boost_chrono \
LOCAL_STATIC_LIBRARIES += ticpp \
    tia \
    tobicore \
    tobiid \
    tid \
    gdf
LOCAL_MODULE           := signalserver
LOCAL_C_INCLUDES       := $(LOCAL_PATH)/include
LOCAL_C_INCLUDES       += $(LOCAL_PATH)/extern/include
LOCAL_C_INCLUDES       += $(LOCAL_PATH)/../boost/include/boost-1_53
LOCAL_SRC_FILES        := #cpp source

include $(BUILD_EXECUTABLE)

除了我，所有子目录makefile文件中列出的Android.mk

TOP_PATH := $(call my-dir)

include $(TOP_PATH)/boost/lib/boost.mk
include $(TOP_PATH)/signalserver/signalserver.mk
.
.

我Application.mk：

APP_PLATFORM          := android-14
APP_ABI               := armeabi-v7a
#APP_OPTIM             := debug
#NDK_DEBUG             := 1

NDK_TOOLCHAIN_VERSION := 4.6
APP_STL               := gnustl_static
APP_CPPFLAGS          := -fexceptions -frtti
